Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664020, here are decompositions:

61 + 8663959 = 8664020
97 + 8663923 = 8664020
151 + 8663869 = 8664020
193 + 8663827 = 8664020
199 + 8663821 = 8664020
223 + 8663797 = 8664020
367 + 8663653 = 8664020
499 + 8663521 = 8664020

Showing the first eight; more decompositions exist.
